NOS2-specific immunostaining in excised murine nasal epithelial tissue. Bright-field view of nasal epithelial tissue from wild-type C57BL/6J mice (a) and IRF-1^–/– mice (b). NOS2-specific fluorescent immunostaining from wild-type C57BL/6J mice (c) and IRF-1^–/– mice (d). IRF-1^–/– mice have a C57BL/6J background. Images are representative of results obtained with four mice of each genotype. Samples processed identically but not incubated with anti-NOS2 antibody showed no staining (data not shown). Objective images (×40).
